Alex Bestler was hiking with a female friend just before 9:00 a.m. at Usery Mountain Park in the Phoenix suburb of Mesa when, without warning, a swarm of bees descended upon him and began relentlessly stinging.

His friend was able to run to the safety of a bathroom, and from there she ran to call for help — but Bestler had already been overtaken by the swarm at that point.

Even the Maricopa County Sheriff's Office seemed surprised at the sudden attack:

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
